Nikwax Cotton Proof is a wash-in waterproofing treatment designed for cotton, polycotton and canvas garments and equipment. Applied directly in the washing machine or by hand, it adds durable water repellency to natural and blended fabrics, restoring their ability to shed rain without altering the look or feel of the material. It also revives breathability and inhibits the rotting of canvas caused by prolonged dampness — a real benefit for field jackets, smocks and groundsheets that see hard use in the field. Cotton Proof can be applied to wet fabric straight from a wash cycle, making it easy to work into a kit-care routine. No tumble drying is required. The formula is water-based and free from fluorocarbons, making it biodegradable, non-flammable and non-hazardous — safe to use at home and compliant with current environmental standards. Available in a 300ml bottle.
